' vented an Improvement in Heel-Bands for Bed Lasting-Machines and the Like, of which the following description, in connec tion with the "accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to lasting machines for boots and shoes of the type commonly.

known as bed chines.

- In assembling and pulling over a boot or shoe preparatory to lasting, especially if' a straight counter be used; it is customary to drive a tack through the back of the counter into the last, at a point close beside the heel seam, and at a distanceofapproximately one inch, more or less from the heel seat, the tack however never )eing completely driven in because it must subsequently be removed. The purpose of this tack is to hold the upper, counter, linings etc. in position upon the last while the shoe is being pulled over, the tack usually being permitted to machines or wiper maremain for the purpose of holding the heel and counter of the shoe upper in position until lasted.

Lastingmachines of the type referred to are usually provided with heel pads of leather or other suitable material, backed by flexible carriers or chains, which are employed to grip the shoe firmly about the heel or counter portion thereof, not only for the purposeof shaping's'uch upper, counter etc.

to t e last but also to hold the last and shoe firmly during the infolding or 'iuturning of' the marginal portions thereof preparatory to tacking the latter down upon the insole.'

At such times it has beenv found that this tack, which has been driven into the back of the heel by its contact with the leather ot the heel pad m'utilates and destroys the latter over a considerable portion of its area because there is no uniformity in the position of the tack. After a tiine'theheel pad becomes, mutilated to such an extent that it ceases --to perform its work perfectly, with a result that renewals, with the attending expense, must fre ity of .work will fall below the required standard. j,

My invention aims to provide a pad which shall be freefrom these objections and the various features .of my invention will be hereinafter disclosed in connection with a machine illustrating one embodiment thereof.

. In the accompanying drawings, Figure 1 heel head of a typical lasting machine of the type referred to, -the same being equipped with a pad illustrating one embodiment of my invention; Fig. 2 is a vertical, longitudi- 'nal section of the head shown in Fig. 1; Fig. 3,-a face View of the pad shown in Fig: 1, partially spread to better show its construction; and Fig. 4 is a vertical section thereof on the dotted line, 4.-4, looking to the left. -..Referring' to the in connection with which my novel 1 ad is employed, may be of any. usual or esired uently be made or. the qualis a plan view, partially broken away, of a drawings, in the particular embodiment of rny invention selected for'illustration herein, the lasting machine,'i

type or. construction. :In the present instance I haveshown a machine of the type illustrated in United States patent to Grandy, No.;5,52,834 ,.dated January 7 1896. The constructionand operation of the machine are so well-knownin, the art that it is unnecessary to furnish afiy detailed description thereof'herein." The wipers ug operated by the handle W, the pad carrying chain c, the levers 85 upon WhlOll it is mounted, the slides 80, and the springs, a: with their associated and cooperatmg parts for closing and opening the pad are and may be as shown in said. patent, like referencecharacters representing like parts in; said patent, so far as said'parts are therein lettered, or equivalent devices of other machines-maybe used if desired. Y e

Referring to Figs3 and 4, the pad proper, marked 11, and composed of one ormore piles of leather o'r.'other suit-able material,1thickened it may be at the iipper edge by an inor desired construction; and the material Whateverthe material or the construction serted rand as shown, may be of'auy suitable the plug in position yet which, by reason i of their shape and elasticity, permit of the insertion and removal of said" plug when necessary by the compression or closing together of the flanges or lips, or one of them. As shown, the front lip or flange 3 is beveled in cross section and the ad jacent area of the opening therefor in-the pad is correspondingly beveled or countersunktov permit said lug to assume 8. nor mal position substantially flat or flush with the inner face of the pad. The back flange or lip rt'may be-thinner, larger and more flexible since its purpose is merely to prevent the plug dropping forward or from position When the pad is broughtplosely against and abouttheheel end of a shoe, the impressionable or rubber plug conformsto the heel end of the last with the upper thereon and to any tack or other project on carried by the last or shoe; for example in Fig. 2, the tack upon meeting the surface of the rubber plug will embed itself therein, the rubber yielding readily before it without damage either to the shoe, the tack or the rubber. This p'ermits the pad proper to be closed tightly and I closely aboutand upon the shoe, not only for proper shaping of the shoe but for sufiicient and better holding thereof to permit of the usual'lasting by the wipers U; at the same or at the opposite end of the last. Upon removal of the shoe, the rubber plug immediately resumes its normal osition preparatory to receiving another s oe, wherein the tack or device may be differently positioned from that of the preceding shoe. This rubber plu when used in connection with a tack at t e back of the heel has a two-fold advantage, namely, it ermits of a better conformation of the pa surface to and about the heel of the shoe and it also prevents bendingof, the tack, with consequent mutilation of the shoe also mutilation of the pad as the pad and shoe are brought together. Another advantage of the rubber plug or its equivalent is that after the heelseat has been lasted and the operator commences to last the toathe heel will oftentimes slip downward on-t-he pad, thereby throwing the shoe out of the proper angle from under the toe wipers where it was firmly set to conform to the shape of the wipers and the toe. The rubber lugholds the heel from slipping and there y is protected against this trouble. Furthermore,

when a lasting pad does not conform to the exact shape of the heel of the last, the last will hit too hard at the back of the outer curve and will not bear closely and tightly around the heel sect of the last, which is necessary to last a good heel. By inserting a section of impressionable or yielding material, for instance soft rubber, in the middle of the pad at the back, there is always sufii cient resistance to rose the counter against the last and yet su cient resiliency to allow the last-to sink into the pad and draw the up er edge closely around the heel seat.

y invention is not restricted to the particular embodiment thereof herein shown by way of illustration, for the same, obviously, may be variously embodied within the spirit andscope of my invention as here disclosed and claimed.

IL A lasting machine containing in combination" lasting devices and a continuous end pad with meansfor supporting it, said pad.
